Patent number: 8315295Abstract: The present invention provides method and apparatus for designing modulation and coding set of communication System. The method for designing modulation and coding set designs a proper set of modulation and coding schemes (MCS), based on probability distribution of the quality of received signal in the communication system, so as to optimize the whole performance of the communication system. The method comprises the steps of: acquiring the probability distribution of the quality of the received signal in the communication system; performing a calculation on the target performance of the communication system based on the acquired probability distribution of the quality of the received signal and a plurality of MCSs, to design a proper set of MCSs for the communication system, so that a region where the probability of the quality of the received signal appears more frequently are provided with more levels of the MCSs.Type: GrantFiled: June 17, 2009Date of Patent: November 20, 2012Assignee: Fujitsu LimitedInventors: Hua Zhou, Jun Tian, Yuantao Zhang, Jinyin Xue
